Embodiment 1
[0023] A kind of preparation method of porous cross-linked polyaniline electrode material, concrete steps are:
[0024] (1) Weigh 4 g of SDS and add it to 100 mL of 0.1 mol / L sulfuric acid aqueous solution, and ultrasonicate at room temperature for 30 min to prepare the sulfuric acid solution of SDS;
[0025] (2) Weigh 0.5 g of aniline, 0.1 g of p-phenylenediamine and 0.2 g of triphenylamine, add them to the sulfuric acid solution of SDS prepared in step (1), stir mechanically for 10 min, and slowly add 20 mL of 0.1 mol / L ammonium persulfate aqueous solution of sulfuric acid (in the sulfuric acid aqueous solution, the concentration of sulfuric acid is 0.1 mol / L), after the dropwise addition, continue to react at 20 °C for 4 h, filter under reduced pressure, and the dark green powdery solids are sequentially Cross-wash with absolute ethanol and deionized water until the filtrate is clear, and vacuum-dry at 60 °C for 24 h to obtain porous cross-linked polyaniline;
